1、英 文 原 文what is ipv6?ipv6 is short for "internet protocol version 6". ipv6 is the "next generation" protocol designed by the ietf to replace the current version internet protocol, ip version 4 ("ipv4"). most of today's internet uses ipv4, which is now nearly twenty y

2、ears old. ipv4 has been remarkably resilient in spite of its age, but it is beginning to have problems. most importantly, there is a growing shortage of ipv4 addresses, which are needed by all new machines added to the internet. ipv6 fixes a number of problems in ipv4, such as the limited number of

3、available ipv4 addresses. it also adds many improvements to ipv4 in areas such as routing and network auto configuration. ipv6 is expected to gradually replace ipv4, with the two coexisting for a number of years during a transition period. some introductory information about the protocol can be foun

4、d in our ipv6 faq. for those interested in the technical details, we have a list of ipv6 related specifications. internet protocol version 6 is abbreviated to ipv6 (where the "6" refers to it being assigned version number 6). the previous version of the internet protocol is version 4 (refe

5、rred to as ipv4). ipv6 is a new version of ip which is designed to be an evolutionary step from ipv4. it is a natural increment to ipv4. it can be installed as a normal software upgrade in internet devices and is interoperable with the current ipv4. its deployment strategy is designed to not have an

6、y flag days or other dependencies. ipv6 is designed to run well on high performance networks (e.g. gigabit ethernet, oc-12, atm, etc.) and at the same time still be efficient for low bandwidth networks (e.g. wireless). in addition, it provides a platform for new internet functionality that will be r

7、equired in the near future. ipv6 includes a transition mechanism which is designed to allow users to adopt and deploy ipv6 in a highly diffuse fashion and to provide direct interoperability between ipv4 and ipv6 hosts. the transition to a new version of the internet protocol must be incremental, wit

8、h few or no critical interdependencies, if it is to succeed. the ipv6 transition allows the users to upgrade their hosts to ipv6, and the network operators to deploy ipv6 in routers, with very little coordination between the two.where can i get an ipv6 implementation for my system?there is software

9、available for most operating systems in common use today. find your favorite os on our list of ipv6 implementations. we also have a collection of "how to install" documents for various systems. what applications run over ipv6 today?many common internet applications already work with ipv6,

10、and more are being ported. see our list of ipv6 enabled applications. benefits of ipv6one of the clearest benefits of ipv6 is the increased address space.ipv4 was defined before it was understood just how explosive the internet would be. consequently available addresses for ipv4 hosts are running ou
